5 claims. (cl. 5 244) i Y This invention relates to a novel bedl spring which is intended to supplant and replace the conventional metallic type, being constructed of a substituted material as for instance wood, plastic material, or other resilient substance.

Heretofore bed springs have been constructed generally of metal, which due to present vconditions is diicult to obtain for that purpose. 4

It is the object herein to provide a bed spring constructed entirely of substituted materialas for instance wood, plastic or other resilient non metallic material.

It is the further object herein to provide a plu rality of formed spring members interposed between the upper and lower portions of the bed` springs which are adapted to maintain a resilient and variably spaced relation therebetween.V

The present invention therefore relates to the various elements hereinafter described and their various combinations as set out in the accompanying drawing of which j Fig. 1 is a perspective view of the bed spring.

Fig. 2 is a top plan View of the upper frame Fig. 3 is a plan View of the lower frame.

Fig. 4 is a side elevational view of the spring member.

. Fig. 5 is a side elevational view of a slightly different embodiment.

Fig. 6 is an elevational view of one upper frame cross bar.

Fig. '7 is an elevational view of one notched lower frame cross bar.

It will be understood that the above drawing illustrates merely a preferable embodiment of the invention, and that other embodiments are contemplated within the scope of this invention.

Referring to the drawing the bed spring as a whole consists of a bottom supporting hollow frame II having cross bars I2, I3 and I4, and-a top supporting frame I5 disposed in variably spaced relation thereto.

Cross bars I6, I1 and I8 are provisioned upon frames I5 providing intermediate supporting means for the longitudinally disposed slats I9 also secured upon and across said frame I5.

Spring members 20 shown in Fig. 4 are made preferably of wood with their ends 2I and 22 bent or looped inwardly and with the central portion 23 flexed or in convex shape as shown. It is contemplated that any other suitable resilient material could be employed which would be adapted to forming in substantially the shape shown in Fig. 4.

Referring to Fig. 1 a plurality of sprmg members 20, 20 and 2II interposed in spaced relat1on l0`4 are notched at 24, 25 and 26 for respectively re between the top supporting frame I5 andthe bottom supporting frame II, are also adapted:

to maintain a variably spaced relation'between said frames. It is understood that springs 20 and 2B may be employed as being sufcient depending upon the size of the Abed springs, how'- ever any number may be employed in carrying out the present invention.

In construction the cross bars I6, I1 and I8 ceiving the end portion 22, the central portion 23 and the other end portion 2| of the spring 20, any suitable means being employed for firmly and immovably securing said portions therein.

Spring 2B is also attached to the bottom sup- `porting member II, being secured within suit`H able -notched portions 21 and 28 within the respective cross bars I2 and I4.

It will be also noted that the notches are suf-v ficiently long and broad as to fully accommodate the depth and width `of the spring member 20 whereby a secure construction is obtained.

It will be noted that leaf spring 26 is secured to the top frame I5 being interposed between said frame and the cross-barsl, I1 and I3. Similar- 1y spring 20 is secured to the bottom frame Ii beingv interposed between said frame and the cross bars I2 and I4.

Cross bars I2, I3 and I4 secured to bottomn are oppositely disposed in variablyV 2U, 20' and 20" against any lateral movement,`

other than the expected tortional stresses that may be received when the bed spring is in use. It wil be understood that all the cross bars are similarly notched for accommodating and securing each of the other spring 20 and 20 Furthermore the number of notches on any cross bar is naturally determined by the number of springs employed.

A slightly different embodiment is shown in Fig. .5 wherein the bottom frame is indicated at 29 with cross bars 30, 3|, 32 and 33, cross bars 30 and 33 being notched at 34 and 35 to receive and secure the spring members 36 and 31.

The top frame 38 has secured thereto the cross bars 39, 40, 4I and 42, all respectively notched at 43, 44, 45 and 46 to receive the end portions respectively-of the springs 3B and 31.

In this embodiment two springs are employed instead of the unitary spring illustrated in Fig. 4; and in the place of the two oppositely disposed cross-bars I3 and 25 shown in Fig. 1, are employed the cross bars 3l, 32, 40 and 4I. It will be understood that the cross bars 30, 3|, 32 and 33 and cross bars 39, 40, 4l and 42 are oppositely disposed in variably spaced relation and provide limiting means against extreme compression or distortion of the springs 36 and 3l.

Likewise it will be understood that the notchedl portions 34 and 35 and also portions 43, 44, 45 and 46 are designed to provide means for snugly. attaching spring members 36 and 31 between the top frame 38 and the bottom frame 29.

It will be understood thatA the present invern tion is adaptable also for the construction and,

springs interposed between said frames, eachv spring consisting of a substantially flat member inwardly. and upwardly bent atits endsinto suh-Y stantially semi-circles, and with the intermediate portion upwardly curved, the ends and central portion thereof being secured between said upper frame and its cross bars, said spring being. also secured between said lower frame and its end cross bars at points intermediate said ends-and saidcentral portion.

2. A bed spring comprised. of an uppei` sup-V portingframe, a central cross bar and cross bars secured adjacent the ends thereof, a lower supporting frame, acentral cross bar andcross bars secured adjacent the ends, thereof, .anda plurality of unitary longitudinally extending springs interposed between said frames, each-spring consisting of a substantially flat member inwardly and upwardly bentat its ends into substantially semi-circles, and with the intermediate portion upwardly curved, the ends of said spring being secured tothe end cross bars of the upper frame, and the central portion ofsaid spring being secured ,tothe centralcross banof said upper. frame,

said spring being also secured to said end cross bars on the lower frame at the points where said springs are inwardly bent.

3. A bed spring comprised of an upper supporting frame, a central cross bar and cross bars secured adjacent the ends thereof, a lower supporting frame, a central cross bar and cross bars secured adjacent the ends thereof, and a plurality of unitary longitudinally extending springs interposed between said frames, each` spring. consisting of a substantially flat member inwardly and upwardly bent at its ends into substantially semicircles, and with the intermediate portion upwardly curved, the ends and central portion thereof being secured between said upper frame and. its cross bars, said spring being also secured between said lower frame and its end cross bars at points intermediate said ends and said central portion, the end cross bars and the central cross bars on said frames being oppositely disposed in spaced relation to limit the flexing movementof said spring.

4. A bed spring comprised of an upper supporting frame, a central cross bar and cross bars secured adjacent the ends thereof, a lower supporting frame, a central cross bar and cross .bars secured adjacent the ends thereof, anda plurality the central portion thereof being secured with-- inthe notches of said cross bars on said upper frame, said spring being also secured within the notches of the end cross bars of said lower frame at: points intermediate said ends and said central 10 portion.

5. A bed spring comprised of an upper supporting frame, a plurality of cross bars thereon, a lower supporting frame, a plurality of cross bars thereon, and a plurality of unitary longitudinally extending springs interposed between said frame-s. each spring consisting of a substantially iiat member inwardly and upwardly bent, at its ends, into substantially semi-circles, with the intermediate portion upwardly curved, the ends and central portion thereof being secured to the upper frame cross bars, said spring being also secured to the lower frame cross bars at points interme diate saidends and said central portion.
